About lossless and point stereo
...ich I don't quite understand and hope I can get some guidance on.
I understand the decoding/decoupling part as it is the same as the one
described in the stereo docs:
From mapping0.c:
/* channel coupling */
for(i=info->coupling_steps-1;i>=0;i--){
float *pcmM=vb->pcm[info->coupling_mag[i]];
float *pcmA=vb->pcm[info->coupling_ang[i]];

float mag=pcmM[j];
float ang=pcmA[j];

pcmM[j]=mag;
pcmA[j]=mag-ang;
